Jacques Daget (30 June 1919, Vineuil – 29 June 2009), was a French ichthyologist. He was a professor at the National Museum of Natural History, in Paris. Several marine species have been named after him. Species named after him Species named after Daget include: * Claroteidae ''Chrysichthys dageti'' Risch 1992 * Cichlidae Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted thi ...

Catfish
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus '' Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phractura
''Phractura'' is a genus of loach catfishes (order Siluriformes) that occur in Africa. ''Phractura'' species are elongated fish with a long caudal peduncle and bony scutes on the sides, back, and belly., this feature giving the genus its name from the Greek ''phraktos'', which means enclosed and ''oura'' which means tail. ''Phractura'' species are often associated with vegetation. The genus was originally given the name ''Peltura'' but this name was preoccupied by a genus of trilobites which the name ''Peltura'' had been applied to by Louis Agassiz in 1846. ''Phractura'' species, like other genera in Doumeinae, have a mouth modified into a suckermouth that allows it to clean to the objects and scrape the surface of the substrate. Species There are currently 13 recognized species in this genus: * '' Phractura ansorgii'' Boulenger, 1902 (African whiptailed catfish) * '' Phractura bovei'' Perugia, 1892 * '' Phractura brevicauda'' Boulenger, 1911 * '' Phractura clauseni'' Daget & ...

Freshwater Fish Of West Africa
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to s ...

Fish Described In 1963
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fis ...
